Embedded Control
PER-EVA900
- Mains power supply (115/230V) with four output voltages including 24V for small external loads
- Eight 24V optoisolated inputs, four of them onto TI4...TI7
- Four 24V optoisolated outputs, source drivers with 200mA load
- Two relays SPDT 230V/8A
- Two RS232 drivers for SER0 and SER1, DB9 and screw terminals
- High speed optoisolated RS485 (BITBUS) drivers for the IUSC
- Precision voltage reference for analog inputs
- Three TTL counter inputs multiplexed with the 24V input TI4
- Input to TI0 for tv-style infrared remote control detector RC5
- Three to six outputs for serial load 4-digit 7-segment displays
- Stepper motor ports without power driver on 10-pin header connector
- LED indicators for power and all 24V inputs
EVA900 is an evaluation board for the NET/900H controller module. It includes power supply, 24V i/o, relays, serial line drivers and more. Some say it's rather a universal control computer than an evaluation device.
EVA900 is 250x111mm in size (or about 10 by 4 inches) and fits into a rail mount cradle for industrial use. Almost any connection uses "Combicon" pluggable screw terminal strips.
- 5V as system voltage for NET/900H and the drivers on EVA900
- isolated 5V for the RS485 line
- 14V unregulated as support voltage for external analog sensors
- 24V to drive the internal relays with about 200mA externally available for feeding the 24V inputs and one or two valves or external relays.
